Feasibility study of "Invariant Information Clustering for Unsupervised Image Segmentation"

In this paper we analyze the performance of a novel clustering objective that optimizes a neural network to predict segmentation. We challenge the reported results by replicating the original experiments and conducting additional tests to gain an insight into the algorithm. We analyzed the efficiency of the clustering objective on a different...

In-plane dynamics of high-speed rotating rings on elastic foundation

Rotating ring-like structures are very commonly used in civil, mechanical and aerospace engineering. Typical examples of such structures are components in turbomachinery, compliant gears, rolling tyres and flexible train wheels. At the micro-scale, rotating ring models find their applications in the field of ring gyroscopes, in which high...

A high-order model for in-plane vibrations of rotating rings on elastic foundation

A new high-order model for in-plane vibrations of rotating rings is developed in this paper. The inner surface of the ring is connected to an immovable axis through an elastic foundation (distributed springs), whereas the outer surface is traction free. The developed model enables the dynamic analysis of the rings on stiff elastic foundation...

Dynamic Finite Element Analysis of Impact Pile Driving Centrifuge Tests

Many farms of wind turbines are being installed worldwide as a response to clean energy targets. These farms are usually installed in offshore environments since limitations of space can be encountered or due to public pressure against the visual disruption that farms can cause in urban areas. These offshore wind turbines are commonly founded on...

Finite Element analysis of soft boundary effects on the behaviour of shallow foundations

The response of a shallow foundation has been investigated by numerical simulations in a series of 1g small scale tests using the Finite Element Method. In this numerical study, special attention has been given to the influence of soft boundaries as a measure to counteract boundary effects, since limitations of space were present in the...
